Description Volker Reichelt 2007-09-17 22:29:39 UTC 
The following invalid testcase triggers a broken diagnostic since at least
GCC 2.95.3:

===================================
int foo(int);

void bar(double d)
{
  foo(d)();
}
===================================

bug.cc: In function 'void bar(double)':
bug.cc:5: error: 'foo(#'fix_trunc_expr' not supported by dump_expr#<expression error>)' cannot be used as a function


The other conversion is broken, too:

===================================
int foo(double);

void bar(int i)
{
  foo(i)();
}
===================================

bug.cc: In function 'void bar(int)':
bug.cc:5: error: 'foo(#'float_expr' not supported by dump_expr#<expression error>)' cannot be used as a function
